While crystalline Tb is a helix antiferromagnet with a Neel temperature of 229K which becomes ferromagnetic at 222K, disordered Tb exhibits a spin-glass transition.
What could possibly be new in MnO 46 years after the discovery of its antiferromagnetic transition?: a spin-glass transition in the 25-50K temperature range.
I consider models with an impurity spin coupled to a fluctuating gaussian field with or without additional Kondo coupling of the conventional sort.
We take another look at two compounds which have been discussed as possible realizations of ``spin ice,{''} namely holmium titanate and dysprosium titanate.
Spin polarized photoemission studies of the Fe 3p core level from a clean Fe(001) surface reveal an exchange splitting of 0.35 eV, considerably less than the 2.46 eV predicted in first principles L
Spin polarized photoemission studies find ferromagnetic growth for Fe thin films grown on both Pd(001) and Cu(001) substrates.
The effect of the electron-electron interactions on the D'yakanov- Perel' spin relaxation rate induced by the spin-orbit interaction is examined in two dimensions.
Electron spin resonance has been studied in single crystal spheres of Eu(x)Sr(1-x)S with samples of nominal composition x = 0.4, 0.5 and 0.54.
Charged carriers with different spin states are spatially separated in a two-dimensional hole gas.
A detailed analysis based on both the double Lorentzian and damped harmonic oscillator forms of the spectral weight function shows that the spin-wave energies strongly decrease as the temperature i
